Angry Birds Rio is the latest from the ubiquitous game franchise. Just like the previous versions, Angry Birds Rio will hook you with hours of bird-flinging fun. If you are burned out on the Angry Birds experience, however, there may not be enough new content to win you over.

In this game the Angry Birds' fellow winged creatures have been kidnapped and hidden away in a warehouse in Rio. You must rescue them the by catapulting your feathered weapons at various contraptions that guard the caged birds. The gameplay is not dramatically different from the original Angry Birds, yet it does have some subtle changes that will interest enthusiasts. For example, many of the puzzles include ropes, hanging shades and elaborate trees that throw an extra challenge when compared to the original game.

The game begins in Smugglers' Den, which is the warehouse where the stolen birds are kept. The next level is Jungle Escape, which has some complex shrubbery trying to prevent you from defeating a new group of enemies. There are 60 levels within the two episodes, with more slots preserved for future updates. Also, those who love to rack up achievements will have plenty of hidden fruit to find.

Some users have expressed anger on App Store review forums over the "ads" that appear throughout the game. Players can upgrade certain gameplay options or purchase merchandise through Angry Birds Rio. It is a slight distraction, although it is easy to ignore them. Angry Birds Rio does, however, have good integration with Game Center, as there are many achievements to unlock throughout the game.

If you are eager to take on new challenges with your favorite birds, then dropping $0.99 on Angry Birds Rio is a no-brainer. For those who have Angry Birds fatigue and have had their fill, there is nothing dramatically new to pull you in. However, Rovio Mobile likely has another hit on its hands with a game that does not seem to be losing its appeal anytime soon.
